Chain Reaction is a puzzle game on flash-game.net in which you click on a molecule and try your best to make the connected molecules move and rotate. At the beginning of the game, you click on a molecule and it will cause chain reactions. Molecules will activate each other if their side atoms are connected. You will get points as the molecule you clicked activates more molecules. You should have a plan before you click on a molecule. But when you click it once more, you will find that the point comes back to zero and you should try again. You can reset the molecules and win more points to break the record of your first click. The objective of the game is to get a chain reaction for as long as possible. Good luck.
